In the present study, it was aimed to perform the morphometric analysis of the hard and soft palate in fetal cadavers and evaluate hard palate asymmetry during the fetal development. The development of the palate was investigated in 40 (21 males, 19 females) fetal materials aged between the 17th and 40th gestational week. In this study, distances between the incisive papilla-staurion (Ip-Sr), staurion-posterior nasal spine (Sr-Pns), incisive papilla-greater palatine foramen (Ip-Gpf) on the right and left sides, Sr-Gpf, and Pns-Gpf were measured. In cases with asymmetry, the ratio of asymmetry was determined in percentage using the asymmetry index. Moreover, angular values between Ip-Sr-Gpf and Ip-Pns-Gpf on the right and left sides were measured, and the right and left side values were compared with each other. The hard and soft palate lengths were measured on the planum medianum. Upon comparing the measured parameters between males and females, the mean values of male fetuses were higher in all parameters, but a significant difference was found only in the Sr-Pns distance among these parameters. Upon comparing the angular data and asymmetry index data on the hard palate between the trimester groups, a significant difference was found only in the Ip-Sr-Gpf (left) parameter. The mean ratio of the hard palate to the soft palate was found as 1.90. It is believed that the obtained data will contribute to studies to be conducted in fields such as plastic surgery, maxillofacial surgery, intrauterine surgery, fetopathology, embryology, anatomy, and obstetrics.

Segmental brainstem myoclonus in ADCK3-Related ataxia: A novel phenomenon?

Segmental Brainstem Myoclonus (SBM) is a rare movement disorder characterized by rhythmic contractions of muscles innervated by brainstem segments. We report a 20-year-old patient with ADCK3-related spinocerebellar ataxia type 9 (SCAR9) presenting with sudden-onset myoclonic movements of the throat, tongue, and soft palate. Brain MRI showed stable findings, including dentate nucleus hyperintensities.

The Strip Gingival Graft (SGG) technique, which involved an apically positioned flap (APF), in combination with an autogenous SGG and a xenogeneic collagen matrix (XCM), demonstrated its efficacy in re-establishing an adequate amount of KM width at implant sites. Nevertheless, it is still unclear whether harvesting the SGG from the palate (pSGG) or from the buccal aspect of natural dentition (bSGG) affects the esthetic outcomes at the augmented implant sites.

: Currently, there is a lack of a comprehensive classification system for soft-palate defects that provides synthetic information to guide functional reconstructive treatment. Our awareness, shaped by extensive experience, of the superiority of myomucosal flaps to fasciocutaneous flaps in functional palate reconstruction has driven us to introduce a new defect-based classification system and propose a new algorithm for reconstructing soft-palate defects using buccinator myomucosal flaps. : Soft-palate defects were classified into five classes.

Digital impressions are increasingly used to manage Cleft lip and/or palate (CL/P), potentially offering advantages over traditional methods. This laboratory investigation sought to evaluate the impact of scanning tip sizes, different scanners, and scanning strategies on intraoral scanning in neonates with CL/P. Ten soft acrylic models were used to simulate the oral anatomy of neonates with CL/P, evaluating parameters such as the ability of different scanning tips to capture alveolar cleft depth, scanning time, number of scan stops, and scan quality.

Background: Mild cognitive impairment (MCI) is a high-risk factor for dementia and dysphagia; therefore, early intervention is vital. The effectiveness of intermittent theta burst stimulation (iTBS) targeting the right dorsal lateral prefrontal cortex (rDLPFC) remains unclear.
Methods: Thirty-six participants with MCI were randomly allocated to receive real (n = 18) or sham (n = 18) iTBS.
